Hello,

I would like to use this OLED display (NHD-0420CW-AW3) I2C driven, the datasheet says to power it @2.8V but for architecture matters, I would like to power it @3.3V.
Could this affect the ageing of the display or lead to any specific troubles ?
If this question has already been asked, please excuse me for creating a new post and could you please refer me to the good post ?

Thank you for your feedback.

Best regards,
Samuel.

  Hi Sam,
  
  The NHD-0420CW-AW3 display can be run using a 3.3V source for Vdd with no issues.  To select running at 3.3V, pin 3 for RegVdd would be grounded.
  
  Best Regards,
